Research Scientist

Dr. Peter G. Mason is a Research Scientist with Agriculture and Agri-Food Canada (AAFC) in Ottawa, Canada. The focus of his research is invasive alien species and classical biological control with particular emphasis on host-range assessment and non-target impacts of parasitoids. This research has been central to formulating a science-based response to a changing regulatory environment for biological control agents worldwide.

  1. The pepper weevil, Anthonomus eugenii is currently the most important pest of pepper crops in North America where it poses a high risk to the cultivation of peppers. To address the current need for new management tools for the pepper weevil, we have initiated a research project which aims to identify the natural enemies associated with the immature life stages of the pest in Canada. From work conducted in 2016, parasitoids belonging to three hymenopteran families including Pteromalidae (Jaliscoa hunteri Crawford, Pteromalus anthonomi Ashmead), Eupelmidae (Eupelmus pulchriceps Cameron) and Braconidae (Nealiolus spp., Bracon spp.) were reared out from field-collected peppers, some of whom represent new records of species able to target the pepper weevil. Together with other ongoing research initiatives, these new natural enemy records may provide opportunities for the development of novel tools for the management of the pepper weevil in North America.
